Nonparametric correlations are based on ranks of data and it can be applied when data does not follow normality assumption (skewed) or outlier exists.
When PCV=35, the predicted Hb=5.589+0.205*35=12.8
PCV is significantly associated with Hb with p-value=0.001
When PCV=35 and age=20, the predicted Hb=5.239+0.097*35+0.11*20=10.8
The observed Hb is 11.1.
PCV is significantly associated with Hb with p-value=0.008 after taking age into account.
One hundred and two patients with acute myelogenous leukemia (AML) in remission were enrolled in a study of a new antisense oligonucleotide (asODN). The patients were randomly assigned to receive a 10-day infusion of asODN or no treatment (Control), and the effects were followed for 90 days. The time of remission from diagnosis or prior relapse (X, in months) at study enrollment was considered an important covariate in predicating response. The response data are shown in next page with Y=1 indicating relapse, death, or major intervention, such as bone marrow transplant before Day 90. Is there any evidence that administration of asODN is associated with a decreased relapse rate?
